4 Claims. (01. 73-270) The object of this invention is to indicate the light supporting springs 32 and 33 are provide quantity of a liquid under pressure that flows to keep the rocking levers l9 and 30 at all times through a pipe between the successive readings in engagement with the valves I8, 22, 23, and ll. of a displacement meter.

1. In a liquid meter for a liquid under pressure, a chamber. a flexible diaphragm therein dividing said chamber into two parts. an inlet valve in each chamber part, an outlet valve located in each chamber part both sets of valves being adapted to be seated in the direction of flow of the liquid. means for alternately opening the inlet valve and closing the outlet valve in one chamber part while the inlet valve is being closed and the outlet valve is being opened in the other chamber part comprising two spring supported caps mounted on each side and in the center of said diaphragm, two levers pivotedly mounted one in each chamber part and one end of each lever being adapted to engage with one of the two spring supported caps, when the diaphragm is displaced to one of its two extreme positions, the other end of each lever being adapted to engage with one of the inlet and with one of the outlet valves, the two inlet valves being arranged in line so that when one is unseated the other valve is seated, the outlet valves being arranged in line so that when one is unseated the other is seated, said levers being so arranged in said chamber that after the diaphragm has travelled, a predetermined distance from its neutral position towards the outer wall of one of said chamber parts the spring supported cap located in said chamber part and mounted on said diaphragm engages with the lever located in said chamber part and said lever engage with and closes the open outlet valve of said chamber part and engages with and opens the closed inlet valve of said chamber part and simultaneously opens the closed outlet valve of said other chamber part and closes the open inlet valve of said other chamber part, the two valves which are thus closed being held closed by the pressure thereon of the liquid under pressure, means controlled by said diaphragm for counting the number of cycles of operation.

2. In a device as set forth in claim 1 in which one of the levers is mounted on an eccentric pivot whereby the quantity of liquid displaced per cycle can be adjusted by rotating the eccentric pivot.

3. In a liquid meter for a liquid under pressure, a chamber. a movabl wall therein dividing said chamber into two parts, an inlet valve in each chamber part, an outlet valve located in each chamber part, both sets of valves being adapted to be seated in the direction of flow of the liquid, means for alternately opening the inlet valve and closing the outlet valve in one chamber part while the inlet valve is being closed and the outlet valve is being opened in the other chamber part comprising two levers pivotally mounted one in each chamber part, one end of each lever being adapted to engage with said moving wall when said moving wall is displaced to one of its two extreme positions, the other end of each lever being adapted to engage with both the inlet and outlet valves of one chamber part when the said moving wall is displaced to one of its two extreme positions, the two inlet valves being arranged in line and the two outlet valves being also arranged in line so that when one valve is unseated. the other valve is seated whereby the liquid under pressure causes the movable wall to move back and forth as the liquid flows through said meter, two spring-loaded caps located one on each side of said movin wall at the point where the said moving wall engages with said levers, a counter adapted to be operated by the movement of said movabl wall,

4. In a liquid meter for a liquid under pressure. a chamber, a movable wall therein dividing said chamber into two parts, an inlet valve in each chamber part, an outlet valve located in each chamber part, both sets of valves being adapted to be seated in the direction of flow of the liquid, means for alternately opening th inlet valve and closing the outlet valve in one chamber part while the inlet valve is being closed and the outlet valve is being opened in the other chamber part comprising two levers pivotally mounted one in each chamber part, one end of each lever being adapted to engage with said moving wall when said moving wall is displaced to one of its two extreme positions, the other end of each lever being adapted to engage with both the inlet and outlet valves in one chamber part when the said moving wall is displaced to one of its two extreme positions, the two inlet valves being arranged in line and the two outlet valves being also arranged in line so that when one valve is unseated, the other valve is seated whereby the liquid under pressure causes the movable wall to move back and forth as the liquid flows through said meter. each said levers including a spring loaded rocking lever pivotally mounted one at the end of each of the said levers, said rocking levers adapted to engage with said valves whereby after one pair of valves has been displaced by said moving wall. force is applied to displace the other pair of valves in addition to that of said moving wall, a counter adapted to be operated by the movement of said movable wall.
